The claims under appeal recite reinforced concrete (claims 1
to 13) or a method of reinforcing concrete (claims 14 to 25).
All claims require that the concrete material to have a
compressive strength of at least 80 Newtons per square millimeter
without fibers (see claim 1, ¶ (c) and claim 14, ¶ (a)).
The applied prior art (i.e., Moens, Kobayashi and Destree)
do not teach or suggest a concrete material having a compressive
strength of at least 80 Newtons per square millimeter without
fibers.
The appellants specification (page 7, lines 15-17) provides
that conventional concretes without fibers have a compressive
strength of about 30 to 50 Newtons per square millimeter.
The examiner determined (Paper No. 14, page 2) that the
claimed limitation that the concrete material have a compressive
